(Cl. 'i6-74) l Claim. l

The present invention relates to power saw iiling benches and it consists in the combinations, constructions and arrangements of parts herein described and claimed.

The invention contemplates the provision of apparatus particularly adapted to the purpose of `filing, gauging power chain saws and consists -essentially of a frame, adjustable means for mounting a chain thereon, a tensioning means for the chain, a guideway for the frame and a .tool holder slidably mounted thereon and hav- .ing adjustable means for holding files and gauges.

It is an object of the invention to provide a vquick and simple means for ling, gauging and jointing the teeth of a chain saw.

.interchangeably and adjustably applied to the :teeth of a saw.

Another object of the invention is the provi- A'sion of means whereby a plurality of saw teeth .may be acted on in a single operation.

Another object of the invention is the provirsion of means whereby extremely accurate filing and jointing may be had in chain saws.

Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawings, in which:

Figure 1 is a vertical elevational view of an apparatus embodying the invention,

Figure 2 is an enlarged detail view, in elevation, illustrating certain parts of the invention,

Figure 3 is a sectional view taken along line 3-3 of Figure 2,

Figure 4 is a plan view of Figure 2,

Figure 5 is a view similar to Figure 2 but showing a diierent tool carried by the apparatus,

Figure 6 is a fragmentary view illustrating a detail of the invention, and

Figure '7 i-s a sectional View taken along line 'l-I of Figure 6.

Referring more particularly to the drawings, there is shown therein a bench having a base I Il, sides I I and a top l2, the sides being preferably braced as indicated at I3.

Angle brackets I4 are rigidly attached 'to the bench top I2 and are provided with upwardly extending ears I5 to which i-s attached by bolts I6 a frame composed of two vertically extending complementary parts Il and I8, the top outer edges of which are provided with rails I9 and the inner top edges of which are cut away as indicated at 2D to snugly receive the base portions 2l of the teeth of a chain saw 22.

A series of locking bolts 23 extend ylaterally through the parts I1 and I8 and are provided with operating handles 24 and provide a means for clamping a section of the saw therebetween.

Extending horizontally from either end of the frame are pairs of arms 25 provided with slots 23 through which are adapted to pass bolts 2l. A grooved idler 29 is carried at the outer end of one pair of arms 25 and a sprocket 3U is carried at the outer end of the other pair of arms 25. The sprocket 30 is provided with an operating handle 3|.

A carriage 32 is slidably mounted on the rails I9 and is provided with a handle 33 mounted atop two pairs of vertically extending arms 34 having vertically extending slots 35 for the reception of thumb screws 36. Interconnecting each pair of arms 3l at points below the top thereof are cross bars 31 provided with set screws 38.

By means of the screws 36 and 38, various tools such as a jointing le 39 or gauge plate 4I) may be adjustably positioned with respect to the teeth lll of the saw.

A spring 42 is fastened to the base IU and carries at its free end an idler pulley 43 to hold the saw tightly upon the apparatus.

In operation, it will be seen that the saw is first mounted upon the pulleys 29, 30 and d2 and the frame in such manner that the bases 2l of the teeth of the saw lie between the complementary parts I'I and I8 of the frame. The parts I'I and I8 are then brought together by tightening the bolts 23 thereby locking a section of the saw in position to be worked upon. Any slack in the saw may then be taken up by adjusting the arms 25, thereafter looking the same in position by means of the bolts 2l. A tool is then positioned in the carriage 32 and, by means of the handle 33, the carriage i-s reciprocated from one end of the frame to the other in the rails I9.

While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modications may be made without departing from the spirit of the invention or the scope of the appended claim.

What is claimed is:

An apparatus for filing, gauging and jointing chain saws comprising a base, a frame mounted upon the base, said frame including two vertically disposed complementary parts, having rails in the top outer longitudinal edges thereof and the top inner longitudinal edges spaced and formed to provide a horizontal trackway therebetween, a carriage slidably mounted on the rails in the top outer longitudinal edges of the frame said carriage being provided with two pairs of vertically extending arms, ai handle mounted rfibove and between said pairs of vertically extending arms to provide means by which said carriage may be moved on said rails, a. tool mounted in the earriage, meghancal Ineens for moving the sa-W *the fjne and jmans'forloekng, sections of the saw in the frame.
